Thank you Xavier. Can you give me an example of the gmond.conf that is located on the cluster "Application Servers"?
Are there any changes needed in the gmond.conf on the gmetad server to allow "Application Servers" to be collected? I think we are getting closer to my problem... thanks all for the help.

That way if that machine is the one that goes down you don't lose visibility into the whole cluster. So here's an example I pulled from our gmetad server (changed the hostnames of course): data_source "Application Servers" app1 data_source "Databases" db1 data_source "ETL" etl1 data_source "Elastic Search Cluster" elasticsearch1 elasticsearch2 data_source "Research Cluster" admin1 admin2 gridname "Mozilla Metrics" I should note that each data source is on different multicast channels, but we always use the default port (8649) for gmond. Hopefully this helps! Cheers, -Xavier On 3/23/11 8:12 AM, Ron Cavallo wrote: > I see. So I need a separate IP AND A SEPARATE PORT.
